To replace the motherboard on iPhone 7 Plus
you will need to remove a lot of screws and the most important step is to fasten all the
screws back correctly
I recommend using a magnetic mat and folding the screws step-by-step during disassembly
Before disassembling, turn off the smartphone and remove the SIM card tray
Take a Pentalobe 0.8 mm screwdriver and remove 2 screws near the charging port
Now take any hairdryer and heat the display surface for 1-2 minutes
Take a suction cup and fix on the display surface near the home button
Next, take a plastic tool and disconnect the display from the case
On the iPhone 7 Plus, the top of the display has latches inside
So, when you opening case pull the display down.
The iPhone 7 Plus case opens like a book, that is, you open the case by folding the
display module to the right.
You can place a suction cup under the display so as not to damage the cable when disconnected.
Now you need a Tri-Wing 0.8mm screwdriver.
Take a screwdriver and remove 4 screws from the metal panel.
Now disconnect the battery cable from the iPhone motherboard.
Next, remove 3 more screws on the top of motherboard and remove the second metal panel.
Disconnect 3 cables of the display from the mainboard of iPhone.
Now lets begin to removing the motherboard and for this you need a Phillips screwdriver.
Also for removing the motherboard, you need Standoff 1.5 mm screwdriver that is in our
HowFixit One screwdriver set.
Disconnect two camera cables from the mainboard and remove the camera from the case.
Unscrew 2 screws, one of which is located on the inner of case.
Disconnect the cable from the board and carefully peel off the cable from the metal panel.
Next, unscrew another 2 screws and remove another metal panel.
Now let's begin to removing the Wi-Fi antenna.
Unscrew 5 screws, one of which is located on the inner of case.
Next, disconnect the two antennas from the motherboard ... disconnect the cable and push
the SIM card eject plunger out.
Again, take a Standoff 1.5 mm screwdriver and remove the last 5 screws that hold the
iPhone 7 Plus motherboard
Remove the motherboard from the iPhone case.
In the description under the video, I left a link where you can
buy a motherboard for iPhone 7 Plus
Now take a short break, drink coffee and return to the installation of the motherboard.
So, let's begin to install the new motherboard on the iPhone 7 Plus.
Install the motherboard in the case and connect all cables.
Check all cables, that all must be above the motherboard.
Next, fasten 5 Standoff screws.
Now move on to installing a Wi-Fi antenna.
Now go to the installation of the second antenna.
Install the metal panel and fasten the 2 screws.
Pay attention to the flexure of the cable and how I install the camera in the housing.
Next, connect the cables to the motherboard and install the metal bracket on top and fasten
2 screws
The iPhone assembled and now you can connect the display and check how smartphone works
with the new motherboard.
Please note that first connect 3 cables of the display to the motherboard and only after
that connect
the battery cable.
As you can see, the iPhone show message that the Touch-ID function does not work and, therefore,
the home button does not work.
That's because the old button is tied to the iPhone 7 Plus motherboard and the new motherboard
that I installed will not work with the old home button at all, it won’t even work when pressed
In this case, there are 2 ways to solve this problem: you buy a new motherboard with the
home button, or you can install the universal home button.
How to install the universal home button; watch in another video, I left a link in the
description under the video.
Next, check the remaining functions of the smartphone and install the SIM card.
If the SIM card not detected, just restart your iPhone
Remove the adhesive tape from the back cover of iPhone.
Now take a cotton swab and medical or isopropyl alcohol, and wipe the iPhone back cover from
the remnants of glue.
Now take a waterproof adhesive tape and put it on the iPhone case.
Using this adhesive tape, you restore resistance to dust and water.
First, connect three display cables to the mainboard of the smartphone, and then connect
the battery cable.
Install metal panels and fasten the screws.
Turn the display over and push it to the back cover.
Fasten the last 2 screws near the charging connector.
Install the SIM card and turn on the iPhone
